PinPoint LE (included with MaximDL) works brilliantly for me, provided the reference coordinates are reasonably close. I liked MaxPoint's ability to build a pointing model for the whole sky, but I think it's designed for higher end mounts than the typical EQ6 - every target lands on chip, but it's about ~ 10 arc min out for me.

EQMOD's N-point model, however, works well for me - provided there's a nearby triangle, most of my targets land within arc secs (or 1-2 arc mins) of centre. Having a script that can automatically slew / plate solve / sync (ala MaxPoint's automap feature) using just AT and EQMOD would be great.

How are you with VB.NET Dave? I've got some code for this in my drift alignment program if of any interest. Ironically I wrote this to do a Maxpoint type "brute force" maths versus mechanical weakness approach for my HEQ5Pro, but ended up understanding how to align my mount better and use EQMOD pier-side syncs such that a few sync points and plate solving are all I need. From memory set it up to map about 20 point each side of the pier. From memory the trickiest bit was using astrometry routines to issue alt/az slew commands (which EQMOD doesn't natively recognise- have to convert to RA/DEC before slew).

Heck, that was a lot of waffle. Ignore if I missed the mark.....
